I would add the following:
- Since I havent seen a 36" wide tank, I am guessing this will be height. If so, that is a really tall tank to maintain and get to the bottom of.
- Mesh top/cover for tank, so that fish dont jump out (they will without it)
- I dont think there is need for LR, dry rock, shelf rock and foundation. You can get foundation and shelf made from dry rock with hammer, chisel, saw and few other tools and time.
- You can use acrylic rods with epoxy to glue rock pieces together.
- As mentioned above, 2 smaller heaters better than 1 big one. With that in mind I will use 2 300W Eheim Jagers on my 110. Add controller like Inkbid or Ranco for each heater
- Pass on GFO, not much need for it. Maybe get it as one of the very last pieces of equipment when you get all other items, fish, corals and so on.
